Customer Ratings & Reviews

The card was easy to install and gives me more flexibility with additional USB ports. I have two USB 3 devices and now I don't have to unplug one to use the other device. I just wish more devices used USB 3 because it is faster. If you have Win 8 you don't need to install any driver for the card, the system will automatically find the driver.

I used this card to add 4 USB3.0 ports to my older XP SP3 machine. The hardware is very good for the price. Everything I've tried, including external disk drives, works well and has very acceptable USB3 speed with this card. The drivers on the supplied disk were a bit dated, but current drivers are easy to find on the internet. The supplied drivers work well enough, but I did have some problems with external hard drives waking properly from S3 sleep mode and hibernation, updating to more recent drivers for 'VIA USB eXtensible Host Controller' (specifically version 6.1.7600.4301 dated 9/25/2013) solved that problem completely, the supplied drivers and the updated drivers I found are neither digitally signed, but neither has produced any hint of instability on my XP machine. VIA is the only chipset I'd consider for USB3.0, and it does not disappoint, transfer rates are very good even when writing to two or more external drives simultaneously.

The expansion card is easy to install and so far has given me no troubles. All 4 ports are functional and do the job as required.

Very much needed to add USB3.0 to my old computer. Probably could've gone with a two ports, but I'm glad I did it. USB2 was taking too long to transfer all my pictures. This is a whole lot quicker.

An older card that still requires a spare power connector, but the software is included and installation a breeze and now I have USB3! Not bad at all and fairly cheap. Software a breeze!

USB-3 expansion card installed easily. Came with the 4-pin molex to SATA power connector, so as long as you have an extra SATA power plug in your system, you don't need any other connectors. Plug and play. All four ports are working. Highly recommended!

way faster than a 2.0 usb port, and having for is really great

This is a cost effective way to upgrade a computer to have USB 3.0 ports. The card comes with a SATA to molex pigtail. Unfortunately my computer P/S does not have molex power connectors nor enough SATA power connections so I had to buy a pigtail with multiple SATA connections to be able to connect the card to the P/S. Not the fault of the card.

I had it for two weeks and I haven't had any problems with it. The transfer rate is great.

added this card to utilize usb 3 speed. didn't have any problems installing although it does have a short power cable.

Installs easily, works as advertised. Description doesn't state that it comes with power cable, but it does.

This product works great! I no longer get the odd message about a device needing more power than what the usb can provide (a usb 2 terabyte backup drive)... And... I now have 4 usb3s, 2 more that in my original card that burned out. The card I discarded did not have a separate power cord connector, this one does. I am very satisfied with the Visiontek USB 3.0 4-Port PCIe Expansion Card.

My mobo (Asus) has a two USB-3 header. The one routed to my front panels are fine. The rear ones, surprisingly, were glitchy. I ran my external HD's into them. They irregularly disconnected on their own. This Visiontek card stays on and on. Awesome.

Simple installation Recognized by OS Drivers installed smoothly connected 3 USB 3.0 drives and everything worked No hassles with drivers or any other issues.

It was easy to install. It did the job of upgrading my computer to 3.0. There still is limitations to the USB, but it will work.

Works. I do find that sometimes it does not like to run more than 2 3.0 devices. Easy install.

not only does this provide more connections, but are 3.0 which gives me faster access to my data. Purchased it to go with my new 4 hard-drive that is USB 3.0.

Only needed two of the 4 ports, but this card allows for future expansion if needed... easy to install and setup, just follow included instructions...

I purchased 4 units installed 2 of them in a new out of the box Windows 10 6th generation i7. Each unit is supposed to plug and play, however comes with an optional power cord and mini installation disc. The slots where the cards plug in take the cards however there is nowhere to plug in the power cord. After speaking with Dell support I was told that the cards should function without the optional power cord. So in my attempt to get the 2 installed cards to work in the PC the PC would not recognize any USB peripherals. Dell support even upgraded the PC with the latest drivers. No go... I am returning the remaining 2 unopened cards

I got 2 usb 3.0 cards, they work fine. The service people in the store were very nice and helpful.
